Fiber optic distributed temperature sensing for the determination of air temperature

This paper describes a method to correct for the effect of solar radiation in atmospheric distributed temperature sensing (DTS) applications. By using two cables with different diameters, one can determine what temperature a zero diameter cable would have. Such a virtual cable would not be affected by solar heating and would take on the...

Monitoring programme for the Maasvlakte 2. Part III: The effects of underwater sound

The Port of Rotterdam is expanding to meet the growing demand to accommodate large cargo vessels. The construction of Maasvlakte 2 (MV2) started in September 2008. One of the licensing conditions is the monitoring of the underwater sound produced during its construction, with an emphasis on the establishment of acoustic source levels of the...

Biogeochemical processes and geotechnical applications: Progress, opportunities and challenges

Consideration of soil as a living ecosystem offers the potential for innovative and sustainable solutions to geotechnical problems. This is a new paradigm for many in geotechnical engineering. Realising the potential of this paradigm requires a multidisciplinary approach that embraces biology and geochemistry to develop techniques for beneficial...

Alternatieve benadering voor maatgevende waterstanden Nederlandse kust

Het stormseizoen is weer begonnen in Nederland. De duinen en dijken langs de Nederlandse kust kunnen in deze periode zwaar belast worden door een combinatie van hoge stormvloed en zware golven. Op dit moment worden deze waterkeringen getoetst en ontworpen met waterstandsgegevens die vooral gebaseerd zijn op statistische extrapolatie van...

On teaching styles of water educators and the impact of didactic training

Solving today's complex hydrological problems requires originality, creative thinking and trans-disciplinary approaches. Hydrological education that was traditionally teacher centred, where the students look up to the teacher for expertise and information, should change to better prepare hydrologists to develop new knowledge and apply it in new...

T-shaped competency profile for water professionals of the future

Global environmental changes introduce new challenges and expose future university graduates in hydrology and related fields to problems of unprecedented complexity and magnitude. The T-shape model is proposed as a generic competency profile guiding the design of university curricula. This model differentiates between cognitive competencies in a...

Improvements in separation of non-ferrous scrap metals using an electromagnetic sensor

This article describes a new method for identification and separation of non-ferrous scrap metals using an electromagnetic sensor that is based on the eddy current principle. The electromagnetic sensor (EMS) is a prototype system that has been developed by Delft University of Technology in co-operation with industry. Experimental results...

Electromagnetic De-Shaling of Coal

The efficiency with which an electromagnetic sensor array is able to distinguish density and ash content of coal and shale mixtures was determined experimentally. The investigated sensor was originally designed for automatic metal detection and sorting in industrial glass recycle processing, where it is widely applied. In coal preparation, the...

Wire Separation From Automotive Shredder Residue

The investigation discussed in this article concerned the removal of wires and cables fraction contained in automotive shredder residue (ASR) through a newly invented device, called the nail roll. Series of tests were carried out with three ASR samples of different origin and the influence of the setting parameters of the machine was analyzed....

The Investigation of Separability of Particles Smaller Than 5mm by Eddy-Current Separation Technology - Part II: Novel Design Concepts

Separability and separation mechanisms of small particles in modern rotating type eddycurrent separators (ECSs) were discussed in Part I. In order to address problems associated with this design concept, a number of novel ECSs, each with a unique design, have been developed. Part II reports on investigation into the separability and separation...
